Not to get too deep - but from a broad, floating high above the sea of humanity, POV - I’m a Dunamis/Bessy hybrid: Good is what promotes cohesion within a group; Evil, that which promotes dissolution.
But that’s a bit too abstract in my book. (Admittedly - my book is written in crayon…)
Inherently is a tricky concept when it comes to our species. You can happily argue that animals are little more than organic automotons, clunking through their programs… But Humans, well, at some point our little genetic driving instructors have turned and said “Right, body/host - you can take off your L-plates, off you go and do whatever you see fit to produce offspring and ensure their survival…” We come out off the assembly line with a selection of default settings - but all of them are ultimately customizable…
At best you could possibly say we are in the most part tentatively predisposed to being a good (member of society), all other things being equal.
So - what is ‘good’ and what is ‘evil’ on an individual basis…?
Good is what we are told is good.
Evil is what we are told is evil.
If there are any genetic/instinctive predisposers - how do they actually work…?
Take the fairly well researched and proven inherrent abhorence of killing another human. Denoted as an ‘evil’ act without seriously mitigating circumstance. I’ll take this as true for arguement’s sake. Is it really a hardwired taboo against killing…? Or is it an innate fear of involving your precious flesh in a situation with potentially, either directly or indirectly, fatal consequence. A selfish wish to avoid present/future pain/harm…?
We do not come out of the womb as doctors or great verbal communicators/psychologists, we do not come out of the womb armed with weapons able to kill beyond the range of sight… How then do we know when we are about to kill someone…? Conflicts over social status/heirachy are pretty much a sure thing in any species - but they seldom go to the point of death - does a Baboon take out a stethoscope mid-fight and check his opponent’s heartbeat…? What do we use as indicators, map-points beyond which our instinct say we should not go…?
I think rather than any deep and meaningful inherent leanings toward morality we are programmed only to recognize and react to certain faces.
There are two facial expressions that apparently we react most strongly to:
Complete submission: The quaking red blubbery face of a downed and thoroughly schooled opponent - his body posture. All of these send a cease and desist order through our animal selves. It can of course be overcome consciously, but it takes an effort of will that implies a hardwired taboo. It makes complete sense - the enemy of your enemy becomes your friend - perhaps you are whupping Joe’s ass right now over a woman or territory, but when the next other-species threat comes along, quite willing to eat both of you - Joe becomes your best mate and brother warrior.
Not so much “Do not kill” as “Do not kill future allies” - not natures fault that we’ve been so successful that outside species threats have become so rare as to be negligable.
Contempt: Marriage counsellors/psychologists have found that relationships fail almost at a rate equivalent to how often one or both of the individuals involved see this expression on the face of their spouse. It apparently overrules the actual verbal components of marital troubles. Someone who holds you so deeply as less than them, or reprehensible according to their own ideals of being - that it shows involuntarily on their faces - automatically discounts you from their group, at an extreme, their species. Then it becomes very easy for them to kill you. Something to be avoided indeed.
So a child, or hell, anyone within a new social group/learning situation - is innately pedisposed to recognize and avoid activity that produces expressions of contempt on the faces of his/her peers.
So:
Good - is that which produces expressions of approval in those around you.
Evil - is that which produces expressions of contempt.
or more succinctly:
Good=
Evil=
Maybe, perhaps, tentatively…
